KPA-11 URANIUM ANALYZER SPECIFICATION

MEASUREMENT TECHNIQUE:

TIME-RESOLVED KINETIC PHOSPHORESCENCE ANALYSIS

LOWER LIMIT OF DETECTION:

0.01 mg/L

ANALYTICAL RANGE:

0.01 mg/L to 5.0 mg/L

RELATIVE STANDARD DEVIATION

Typically 2-3% above 0.1 mg/L & 7-10% below 0.1 mg /L

	NITROGEN		DYE
PEAK POWER	40	kW	5
MAXIMUM POWER	2	mW	0.5
PULSE LENGTH	3	ns	3
PULSE ENERGY	120	mJ	20
REPETITION RATE	1-20	pps	1-20
WAVELENGTH	337	nm	400-900

MEASURED WAVELENGTH:

515 nm +/- 10 nm

DETECTORS:

Photomultiplier tubes operate in photon counting mode. High humidity can affect tube performance. A controlled environment is recommended for 40% or greater humidity.

SAMPLE REQUIRED:

1-2 ml

ANALYSIS TIME:

1-3 minutes per sample is typical

SOFTWARE:

The KPA-11 is controlled by KPAWin running on a personal computer. Call for the current recommended PC configuration.

SYSTEM CONTROL PARAMETERS:

A) Number of laser pulses per analysis; 1-9,999
B) Time gate (interval) width; 1ms-4 ms
C) Number of time gates (intervals) used in calculation is 1 to 512.
D) Number of time gates used in calculation is 2-512.

DATA COLLECTION:

Photon counts are accumulated for each time gate (interval) for each sample analysis.

DATA PROCESSING:

Intensity Data are corrected for background, variations in laser power and coincidence. Intensity intercepts are calculated by linear least-squares regression. Results are quantified by external or internal calibration.

DATA EVALUATION:

Quality control and performance criteria are configured by laboratory personnel. Off standard conditions are reported with the interpreted data and alarmed.

DIMENSIONS

13.6 cm high; 48 cm wide; 53 cm deep

WEIGHT

17 kg (shipping weight 21 kg)
